Incidentally, if you haven't followed him in awhile, Bear Grylls (Man vs. Wild) crushed his shoulder while kite-skiing (I know, *what?!*) on an unrelated Antarctic expedition. I knew he'd been injured but ouchies, looking at the x-ray (at bottom of page) -->
Bear's Blog
Here's his blog regarding the expedition, including his rescue and some info on the purpose of the particular expedition (sponsored by an ethanol fuel company, showcasing alternative, "greener" energy sources. I didn't realize he had a conservationist's heart, what with all the raw critter eating ;-)

PS: According to this article --
Man Vs. Wild's Bear Grylls: Force of Nature : People.com -- "when not in survival mode, he (Grylls) is a vegan." Who'd a thunk it?! Kudos to him for that. I'm a Texan... gotta have my meat!
